Numerical Study of Different Tools in High-Speed MQL Cutting of Aluminum Alloys

Aluminum alloys have been extensively used in aerospace, machinery, transportation, and other industries due to their superior strength, relatively low weight, and outstanding thermal conductivity. High-speed cutting (HSC) and minimum quantity lubrication (MQL) techniques have been widely applied for the machining of aluminum alloys. This paper investigates numerically the influences of various geometrical tools on the cutting behaviors, in particular, the cutting forces/temperature of aluminum alloys. The effects of the rake angle and the friction coefficient are examined by simulations based on the orthogonal cutting mode. The findings of the numerical analysis may guide the design of cutting tools in high-speed MQL cutting for aluminum alloys.
